BRUSH DRILLING AND/0R FILLING MACHINE WITH WORKPIECE HOLDER AND STORAGE RECEPTACLE FOR THE WORKPIECES Filed Oct. 11. 1963 11 Sheets-Sheet 11 United States Patent 9,8 0 4 Claims. (Cl. 300-11) This invention relates to a brush drilling and/ or filling machine which has a workpiece holder and a storage receptacle or magazine for the workpieces. It relates particularly to a device by means of which even larger brush bodies can be taken from a magazine, automatically clamped and brought into position for working. The clamping means are to be easily exchangeable so that brush bodies of different shapes can be worked without considerable changes on the clamping means.

The invention provides a brush drilling and/ or filling machine which comprises at least one magazine for the brush bodies and an adjustable workpiece holder movable under the delivery opening of the magazine into a receiving, working and possibly an ejecting position, said workpiece holder consisting of a base frame, at least one abutment rail on said base frame and at least one adjustable clamping jaw cooperating with said abutment rail.

The magazine can preferably be arranged in substantially vertical position and carry at its delivery end a supporting system which can be opened for releasing the lowermost workpiece.

This supporting system preferably consists of two rotatably mounted flat slides arranged directly underneath the delivery end of the magazine and the blocking surfaces of which can be swung into and out of the outlet of the magazine by means of an adjusting device.

A' clamping pin or the like can also be arranged longitudinally shiftable on the magazine opposite one of the end faces of the next to the lowest workpiece so that the pushed-in pin can clamp this workpiece tightly in the magazine. The clamping pin loaded with a return spring, should preferably be connected with the adjusting device for the slides so that the opening movement of the slides shifts the pin into clamping position before the lowermost workpiece is released. At the same time it is advantageous that, for transmitting the movement of the slide adjusting device to the clamping pin, a flange on the adjusting device is employed which bears against a feed spring bearing against the pin.

The adjusting device and/ or the clamping jaw of the workpiece holder are each connected with a pneumatically operated piston.

The workpiece holder is preferably pivotally mounted; if desired it can be slidably guided in a carriage guide or the like. The workpiece holder is preferably connected to a pneumatically operated piston which can effect the swinging or shifting of the workpiece holder.

The brush drilling and/ or filling machine can also have adjustable abutments for the workpiece holder which are preferably provided with a buffer disc. The extreme positions of the workpiece holder are adjustable by means of these abutments.

If desired, two storage receptacles or magazines with their related workpiece holders can be mirror symmetrically arranged side by side and the holder movements so tuned to each other that the drilling or filling tool can pass from the holes last worked in a workpiece accommodated in the first holder, directly to the neighbouring holes of a workpiece accommodatedin the second holder and, after completing these, can return to the first workpiece holder filled with a fresh workpiece. Thereby each holder can be charged with a fresh workpiece when the tool is working on the other holder. If desired blocking slides can be arranged on the workpiece holder which block the storage receptacle from below when the workpiece holder is not in receiving position underneath the receptacle.

If desired the supporting system for the storage receptacle which can be opened, may consist of at least one resiliently mounted slide which is provided with an abutment for the workpiece holder so that this forces the slide out of the range of the delivery end of the storage receptacle when the workpiece holder moves into the receiving position.

A spring serving as ejector can also be provided in the workpiece holder. An electric switch is preferably arranged in the range of the brush body in position for working, which switch can stop the brush drilling and/ or filling machine when there is no brush body in the workpiece holder.

FIG. 16 is a diagram corresponding to FIG. 15 for a machine with drilling and filling tools arranged vertically.

As shown in FIGS. 1 and 2, a storage receptacle or magazine indicated generally by the numeral 1 has vertical guide rails 3 between which a plurality of brush bodies 2 to be worked can be piled. At the delivery end 5 of the storage receptacle 1 a workpiece holder indicated generally by the numeral 6 is arranged which has a base frame 7. On this base frame 7 an abutment rail 8 as well as two guide rails 9 are fixed yet can easily be detached. The base frame 7 also carries an adjustable clamping jaw indicated generally by the numeral 10 which consists of a carriage 11 guided in the base frame 7 and a shaped plate 12 detachably mounted thereon. By this manner and means, a considerable part of the idea of the invention is realized, namely to produce a combination between a storage receptacle, an automatic loading arrangement and a workpiece holder, whereby the storage receptacle enables automatic loading and the workpiece holder 6 a very accurate adjustment in the working position and the receiving position.

Directly below its delivery end the storage receptacle 1 has a supporting system indicated generally by the numeral 13, and destined to receive the undermost workpiece 2a (FIG. 2). This supporting system 13 comprises two flat slides 16 and 17 pivotable at 14 and (FIG. 6), the blocking surfaces 18 and 19 of which can be swung into and out of the outlet aperture of the receptacle. This swivel movement is effected by an adjusting device indicated generally by the numeral 20 having a sliding block 21 in which the bent rear ends of the slides 16 and 17 engage. When the sliding block 21 moves forwards towards the storage receptacle 1, the slides 16 and 17 open, as shown in FIG. 6.

In the storage receptacle 1 a clamping pin 23 is arranged at the height of the end face 22b of the next to lowermost workpiece 2b and shiftable in longitudinal direction. The clamping pin 23 has its front end mounted in a bore 24 in one of the guide rails 3 of the storage receptacle and its rear end in a bore 25 of a flange 26 forming part of the sliding block 21. The clamping pin 23 carries a set screw 27 and a return spring 28 which bears at one end against the guide rail 3 and at the other end against this set screw 27. It also carries a feed spring 29 which bears against the outwardly directed face of the set screw 27 and against the flange 26 of the adjusting device 20. This is connected up with a pneumatically operated piston (not shown).

In the embodiment illustrated in FIGS. 1 and 2 the base frame 7 of the workpiece holder 6 has two flanges 290 and 30 which are pivotable in bearing eyes 31 fixed on the machine frame. The piston rod 32 of an articulated pneumatic cylinder and piston means 33 engages the flange 30 so that the workpiece holder can be swung through an angle of 90 when this aggregate 33 is actuated, as shown in FIGS. 3 and 4.

The embodiment illustrated in FIGS. 1 to 7 operates in the following manner:

The storage receptacle 1 is first filled with the workpieces namely the suitably prepared brush bodies 2, when the supporting system 13 is closed. The lowermost brush body, designated by 2a in FIG. 2, rests on the blocking surfaces 18 and 19 of the slides 16 and 17 located in closing position. The workpiece holder 6 assumes the position illustrated in FIG. 1 facing the delivery end 5 of the receptacle 1. Now if the adjusting device 20 moves in the direction towards the receptacle 1, the flange 26 first presses so strongly against the feed spring 29 that its force becomes greater that that of the return spring 28 and presses the clamping pin 23 against the next to undermost workpiece 2b (FIG. 1). As the adjusting device 20 continues to move forward, the sliding block 21 causes the slides 16 and 17 to open in tong-fashion and clear the outlet opening of the storage receptacle 1 (FIG. 6). The lowermost workpiece 2a in the storage receptacle 1 then drops on the holder 6 ready to receive it, where it is designated by 20 in FIG. 1. While the delivery end 5 of the storage receptacle 1 is free, the clamping pin 23 presses the workpiece 212 next to the bottom in the receptacle 1 against the guide rails 3 so that it and all the brush bodies 2 above it, are blocked in this position until the supporting system 13 has again closed the outlet opening of the receptacle 1. This takes place during the return movement of the adjusting device 20 and the swinging movement of the slides 16 and 17 connected therewith. In moving back, the adjusting device also reduces the pressure exerted by the flange 26 participating in this return movement, against the feed spring 29 so that finally the return spring 28 is able to disengage the clamping pin 23 from the brush body 2b to such an extent that this is freed and drops under its own weight on to the blocking surfaces 18 and 19 of the holder 13. The set screw 27 enables the clamping pin 23 to be adjusted so that it engages at the proper time and with sufficient force.

The guide rails 9 mounted on the base frame 7 of the storage receptacle 1 guide the brush body 2 dropping out of the receptacle 1 in such a manner that it comes into the proper position on the folded up holder 6 (FIG. 1). The pneumatically operated piston P slidably guided in a cylinder C and connected by means of piston rod R with the clamping jaw 10 moves the latter into its closing position. At the same time the brush body resting on the holder 6, which is now designated by 2c, is shifted by the shaped plate 12 against the abutment rail 8 and tightly gripped by the clamping jaw 10 and the abutment rail 8. Thereupon or already during this clamping opera tion, the pneumatic means 33 becomes operative and swings the workpiece holder preferably through an angle of 90 into the position illustrated in FIG. 2. In this position the brush body is worked, that is, is drilled and/or filled (see FIGS. 2 and 7). When the work on the brush body 20 is terminated, the same piston pulls back the clamping jaw 10 so that the brush body tips out of the holder 6 under its own weight and drops into a receiving receptacle (not shown). If desired a special ejecting device 37 may also be provided. The ejecting device 37 may be pneumatically operated and it may include a cylinder C slidably guiding a piston P therein having a piston rod R extending through an opening in the frame or plate 7 of the workpiece holder 6 in engagement with a brush body resting thereon so as to eject the body after the clamping jaw 10 has been released and when pressure fluid is fed into the lower end of cylinder C The pneumatic means 33 thereupon returns the workpiece holder 6 into its folded up position shown in FIG. 1, and the cycle of operations can commence afresh.

In order to enable the extreme positions of the Workpiece holder to be accurately set, adjustable abutments 34- are provided on the brush drilling and/or filling machine, which abutments consist of screws and carry buffer discs 35 on their heads. With the aid of these abutments 34- the position of the workpiece holder 6 can be very accurately adjusted in the working position (FIGS. 2 and 4) in a single manner. This is very important for enabling the drilling and/ or filling operations to be car ried out smothly. However, another extreme position can also be accurately adjusted in the case of the work piece holder which is generally provided for two positions, so that a reliable picking-up of the brush body 2 from the storage receptacle 1 is ensured. The construction as proposed by the invention not only allows the guiding and abutment rails 8 and 9 as well as the shaped plate 12 of the clamping jaw 10 to be easily exchanged, but also a readjustment and adaptation of these guiding and clamping means. Even the whole holder 6 can also be easily exchanged.

In FIGS. 8, 9 and 10 a slightly modified form of construction is illustrated. Therein the workpiece holder is not pivotably mounted but is arranged in carriage guides 36. In this case the workpiece holder 6a also has an ejecting device 37 which is capable of ejecting the brush body 2c out of the holder 6a after it has been Worked and released by the clamping jaw 10. Also in this form of construction the workpiece holder 6a located under the storage receptacle 1 takes over the lowermost brush body and clamps it in the manner already described. During or after the clamping operation the workpiece holder carries the brush body 20 clamped on it into the position for working as can be seen from FIGS. 9 and 10. The shifting 'of the holder 6a is again effected by the pneumatic aggregate 33a.

In the embodiment illustrated in FIGS. 8 to the supporting system 13 which serves for temporarily closing the receptacle 1 is composed of two blocking rails 38 mounted on the workpiece holder. These rails efiect the horizontal movement of the holder 6a and close a delivery opening 5a of the receptacle 1 when the workpiece holder 6a is not in receiving position. Instead of the carriage guides 36, guide rails can, for example, also be used. The horizontal displacement of the workpiece holder 6a is employed when both the drilling and/or filling tools as well as the storage receptacle or receptacles are arranged vertically, as shown in FIG. 10 in which the working head of a filling tool 39 is indicated diagrammatically (see also FIG. 16). It is evident that the workpiece holder 6a can also be shifted transversely to the storage receptacle. The machines operating with horizontal guiding for the workpiece holder 6a also have abutments 34 by means of which the end positions of the holder 6 are adjustable.

According to a further development of the invention two storage receptacles 1b and 1c are arranged symmetrically side by side in the embodiment illustrated in FIGS. 11 to 13. Underneath these receptacles workpiece holders 6b and 6c are arranged which correspond substantially to the swing workpiece holder 6 described in connection with FIGS. 1 to 7. Each of these holders 6b and 60 has a base frame 7b and 7c, respectively, which carries a guide rail 8b, 80 as well as a clamping jaws 10b, 100 provided with a suitable shaped plate 12b, 120. The clamping jaws are again connected with a penumatically adjustable piston P The workpiece holders 6b and 6c are symmetrically assembled corresponding to the symmetrical arrangement of the storage receptacles 1b and 1c. They are also provided with ejectors 37b and 370, respectively.

The brush drilling and/or filling machines which are provided with two storage receptacles are designed for working toothbrush handles 40 and 41. These have a relatively small number of holes. Consequently in the case of such workpieces it is important that the dead intervals necessary for the change from one work piece to another during the working operation be kept as short as possible. To attain this, it is proposed that, under the mirror symmetrically arranged storage receptacles 1b and 1c, the movements of the workpiece holders 6b and 6c are adapted to each other in such a manner that the drilling or filling tool can pass over from the last holes 45 to be drilled or filled in the workpiece 42 in the first holder 6b, directly to the neighbouring holes of the workpiece in the second holder 60. When this workpiece is finish worked the tool must then return to the first holder 6b carrying a fresh workpiece. For this purpose therefore an alternating operation of the two workpiece holders 6b and 6c is necessary, whereby during the changeover of the tool from the toothbrush handle 42 clamped in the holder 6b, to the toothbrush handle (not shown) clamped in the holder 60, both holders 6b and 6c must be in the downward swing working position. Naturally both the storage receptacles 1b and 10 as well as the holders 6b and 60 associated therewith must be so arranged that the ends of the workpieces 4042 to be worked are situated side by side. The exchange of the workpieces 40-42 is effected in one holder, for example, the holder 60, when the tool is working on the other holder 6b. This position is shown in FIG. 11 where the brush handle 41 located in the receptacle 1c is just held by a blocking rail 380. As soon as this uncovers the outlet opening 50 of the storage receptacle 1c, the toothbrush handle 41 will drop under its own weight onto the workpiece holder 60 ready to receive it and there be tightly clamped by means of the abutment bar 80 and the shaped plate 12 of the clamping jaw 10c. During this operation or directly following the same, the holder 60 then swings out of the position shown in FIG. 11 into its Working position.

This is shown in connection with the holder 6b in FIGS. 11 and 12.

The supporting system 13 for the workpieces 40 and 41 in the storage receptacles 1b and 1c is formed by blocking rails 38b and 380 which are curved to correspond to the movements of the workpiece holders 6b and 60, as shown in FIG. 13. This figure shows the holder 60 in receiving position and the holder 6b in working position.

The brush drilling and/ or filling machine possesses the advantage over the similar machines hitherto known that brushes of all kinds, above all even larger brushes can be taken automatically from a magazine and clamped in a workpiece holder which feeds them to the drilling and/ or filling tools and ejects them after they have been worked. At the same time accurate adjustment of the workpiece holders is possible, which can be easily exchanged or converted so that they can be used for clamping workpieces with different contours. The structural elements used in the machine proposed by the invention are extremely simple to assemble and consequently can be serviced and repaired by working staff such as is normally available. The movable elements can be driven by compressed air which is available in any case in numerous important factories. The control of the pneumatically driven pistons and the like, is eifected by means of conventional electro-pneumatic controlling devices. The machine proposed by the invention is simple to manufacture, strong and enables the use of many similar parts even in the case of different types of brush drilling and/or filling machines.

FIG. 14 shows another form of construction for the supporting system for the lowermost workpiece in the storage receptacle 1. Here the supporting system consists of at least one resiliently mounted slide 50' which has an abutment for the workpiece holder 6. When this is in its operative position the slide 50 engages under the storage receptacle 1. If, on the other hand, the workpiece holder 6 is swung into its receiving position underneath the storage receptacle, as shown in FIG. 14, the holder 6 comes into contact with the abutment of the slide 50 and pushes it aside so that this slide clears the delivery end of the storage receptacle when the workpiece holder has assumed its receiving position under the storage receptacle.

Both pneumatically operated ejecting devices 37 and also ejecting devices consisting of a spring (not shown) can be accommodated on the workpiece holders 6, 6a and 6b. Spring ejecting devices of this kind are placed under slight tension when the workpiece enters the workpiece holder. When the workpiece holder is in its swung-out position it enables the finished workpiece to be removed from the clamping device.

In FIG. 12 two electric safety switches 51 are shown which are located in the range of the brush body located in position for working. These known electric safety switches enable the whole machine to be brought to a standstill when there is no brush body in the workpiece holder 6.

Finally it is also mentioned in connection with FIGS. 15' and 16 that they each show a brush drilling and/ or filling machine in side elevation in the form of a rough diagram, FIG. 15 showing a machine in which the drilling and filling tools are arranged horizontally and FIG. 16 a machine in which these tools are vertically arranged.
